Evolution Series

Evolution Excel®

The Evolution Excel® features the best of InSinkErator's grinding and SoundSeal Plus™ noise-reduction technologies, handling more volume and more types of food waste while making 60% less noise than standard disposers. See and hear the Excel®.

Our powerful food waste disposers are the right choice when replacing an existing unit or designing a brand-new kitchen. You can choose between five Evolution models, including Evolution Septic Assist®, designed specifically for homes with septic systems.

With an InSinkErator food waste disposer in your kitchen, chicken bones, fruit rinds, coffee grounds and more can go right in the sink -- where they're virtually liquefied to safely flow into your sewage system or septic tank. You'll enjoy a cleaner food preparation area, and less bagged garbage cluttering your home.

Food waste disposers provide an environmentally responsible alternative to transporting food waste to landfills. And they can help reduce greenhouse gas emissions. At capable wastewater treatment plants, food waste can be converted to biosolids and used as fertilizer. Capable plants can also capture methane gas and recycle it as an energy source. (Check the plant in your area.) Learn more about disposers and the environment.

What's more, if you've never owned a food waste disposer, you're in for a pleasant surprise. InSinkErator disposers are economical to operate: in fact, they're among the least expensive installed kitchen appliances.

Rated 4.8 out of 5�by 436 reviewers.
Rated 5 out of 5�by So quiet and efficient. I had a disposal and after it plugged up twice with potatoe peels, the repairman said that disposals weren't made for peels. Bull!! I got the insinkerator and was so impressed. It was so quiet, I had to check that I turned it on. I have ground up things that I never imagined like small bones, banana peels, asparagus, celery and lots of potatoe peels. I would recommend this product to anyone and I just love it! As to installation, we had a plumber do it because of our back problems to get under the sink. However, he didn't seem to have a problem and was done replacing our old one within an hour or so.

Rated 5 out of 5�by Great Disposal and Would Recommend to Anyone Product has been installed for a year. Excellent!! January 20, 2014
Rated 3 out of 5�by Owned Several I've owned several of these, and perhaps that's the problem. They warranty is good, but I have had to replace mine a number of times. In-sink-erator does stand behind them. The but is you have to take them to an authorized dealer for warranty. Mine seem to fail when we are having a family holiday event. They are top of the line price-wise, and they do the job of grinding (with minimal noise) better than any other I've tried. They are easy to remove, but though to install. That isn't because the procedure is hard, it is because they are really heavy and hard to get set on the ring in a tight space such as under the sink, where one put a disposal. January 3, 2014
Rated 5 out of 5�by This product is quiet and efficient. This product is very quiet and efficient. It was an excellent choice for our refurbished kitchen. January 3, 2014
Rated 5 out of 5�by Quiet, effective unit. This unit outperforms our previous builder's grade unit, by a huge margin. It is essential if one wishes to hold a conversation in the kitchen, while running the disposal unit, or perhaps sleeping in the next room/ January 2, 2014
Rated 5 out of 5�by Excellent disposal - easy installation, quiet, no leaks! Compared to the 1.25 HP Titan disposal purchased at Costco that it replaced (when one of the pieces broke off in the grinding chamber after about a year -- warranty might have covered replacement, but why would I want another one?), it is absolutely WONDERFUL! Easy installation (Titan was hard to install and then leaked -- clearly not designed for cast iron sinks), NO leaks, and is incredibly quiet. In fact, if I am to have any sort of complaint, it is that it is so quiet that there was one time that I turned off the water for a moment and didn't realize that the disposer was still running. It has taken in everything that we've "fed" it without any problems with plugging (a problem that we did have with our old ISE Badger) -- apparently the multi-stage grinding system is VERY effective.

Rated 5 out of 5�by Quiet My husband installed the new garbage disposal in about 2 hours. It was very easy. We like how quiet it is. December 26, 2013
Rated 4 out of 5�by This disposal is very quiet, you can watch TV while using this disposal. Only one problem, one of the blade of the disposal got stuck after approximately one month of use and the unit vibrated badly. I saw rust spots in the area around the blades, this may had caused the blade to stuck. I used a screw driver to push on the blade and WD40 to un-stuck the blade. It has been working ever since.
